BEN F. CALDWELL... John Caldwell, the second son of the Honorable William Caldwell and father of our subject, was born near Nicholasville, Jessamine County, Ky., January 21, 1807.  About 1827 he removed to Carrollton, Greene County, Ill., and there on January 23, 1834, he was married to Mary Jane R. Davis.  That lady was born in Boyle County, Ky., January 15, 1815.  Her grandfather, Cyrus Davis, was born in Wales in 1726, and married Sally Harris.  They emigrated to Boyle County, Ky., where both died, the husband February 21, 1811, and the wife some time previously. Their son, Robert Harris Davis, was born in Virginia about 1775 and on December 27, 1797, married Mary Lewis Robards, who was born in Goochland County, Va., about 1778.  Mr. Davis died in Boyle County, Ky., September 16, 1818, and his widow passed away in the same county September 6, 1829.  When their daughter, afterwards Mrs. Caldwell, was a young lady she went on horseback from Danville, Ky., to Tallahassee, Fla., returning by the same route and continuing on to Carrollton, Ill., a trip of 2,000 miles.  John Caldwell with his family came to this county in April, 1853, and located on a farm that had been purchased by his father some years before.  It is nine miles southwest from Springfield and one and a half miles north of the village of Chatham, on section 36, in the town of Curran.  The new occupant made further improvements and died there after a painful illness, August 1, 1863.  The widow with her son, our subject, who was fifteen years old the day his father was buried, still reside on the farm.  The children of John and Mary J. R. Caldwell were five in number and were named William C., Jane, Betsey, Henry C., and Ben F.  The first-born is proprietor of the Loami Mills and also a farmer, his residence being in the village of Loami.  All the others except our subject are deceased.  Ben F. Caldwell was born in Greene County, this State, August 2, 1848, and came with his parents to this county in 1853.  He received a thoroughly practical education in the common schools and in the graded schools of Chatham, but was deprived of a higher education, as on the death of his father he was obliged to render assistance to his mother in the management of his father's estate.  On reaching maturity, Mr. Caldwell became an active business man and by careful and judicious management of the two hundred acres left by his father added to the farm until he now owns one thousand acres, all adjoining and situated in the town, of Curran and Woodside.  The estate is highly improved and is one of the finest among the many fine farms in the State.  Near the original home, in 1876, Mr. Caldwell and his mother erected an elegant dwelling house.  It is conceded to be one of the best farm houses in the State, and few residences even in the larger cities, are so well or conveniently constructed or so elegantly furnished.  It is supplied with every modern convenience, lighted by gas, heated by steam, and supplied with water.  Here with his family, Mr. Caldwell enjoys life, royally entertaining his friends when they call...
